### Summary

The test depreciation test can't be used right now until the new version
of qiskit isn't largely used. It come from we still used the old way to
check the qiskit version of projects in order to not get the terra
version. It will be able to revert this change when qiskit terra gonna
totally disappeared.

Cause :

https://github.com/Qiskit/ecosystem/blob/0212a863ffdc1ece3964285ac295db6565500332/ecosystem/templates/configured_tox.ini#L32
As we want to keep the qiskit version and not the terra version we have
to keep it this way for now.


### Details and comments
- [x] Update test `test_tests_runner_on_simple_repo`
- [x] Add test `test_website_builder`

Closes #572
